00:00:02,600 --> 00:00:08,580 |
|
بسم الله الرحمن الرحيم محاضرتنا لليوم استكمالا |
|
|
|
2 |
|
00:00:08,580 --> 00:00:16,000 |
|
لموضوع ال bio mechanics of muscles هناخد اليوم ال |
|
|
|
3 |
|
00:00:16,000 --> 00:00:22,320 |
|
muscle variables و .. و نشوف إيش تأثير ال .. ال |
|
|
|
4 |
|
00:00:22,320 --> 00:00:25,580 |
|
different variables of the muscle على ال strength |
|
|
|
5 |
|
00:00:25,580 --> 00:00:31,000 |
|
في عندنا ال muscle length رقم واحدفي عندنا two |
|
|
|
6 |
|
00:00:31,000 --> 00:00:34,600 |
|
main type of muscle length في عندنا ال resting |
|
|
|
7 |
|
00:00:34,600 --> 00:00:39,100 |
|
length و عندنا ال equilibrium length ال resting |
|
|
|
8 |
|
00:00:39,100 --> 00:00:47,010 |
|
length هو عبارة عن ال ..العدلة طول العدلة ال |
|
|
|
9 |
|
00:00:47,010 --> 00:00:51,270 |
|
length of an uncontracted and unstretched muscle |
|
|
|
10 |
|
00:00:51,270 --> 00:00:56,830 |
|
طول العدلة الطبيعي without any contraction ولا |
|
|
|
11 |
|
00:00:56,830 --> 00:01:01,470 |
|
stretching of the muscle أما ال equilibrium length |
|
|
|
12 |
|
00:01:01,470 --> 00:01:05,320 |
|
بدنا نتخيل أنه بناخد isolated muscleهو ال length |
|
|
|
13 |
|
00:01:05,320 --> 00:01:09,340 |
|
of an isolated muscle and contracted لو عزلنا |
|
|
|
14 |
|
00:01:09,340 --> 00:01:12,620 |
|
العضلة هذه شيلناها من أطرافها التنين ال origin and |
|
|
|
15 |
|
00:01:12,620 --> 00:01:19,290 |
|
ال insertion بنلاقي العضلة ابتأثربتقصر تقريبا 10% |
|
|
|
16 |
|
00:01:19,290 --> 00:01:26,570 |
|
من طولها لو كان طول العضلة 30 cm فهي بتقصر 3 cm |
|
|
|
17 |
|
00:01:26,570 --> 00:01:29,810 |
|
تقريبا لو شلناها من المكان لأن هي بتكون بين ال |
|
|
|
18 |
|
00:01:29,810 --> 00:01:34,830 |
|
original و ال insertion مجدودة حتى لو كانت في وضع |
|
|
|
19 |
|
00:01:34,830 --> 00:01:38,630 |
|
الراحة يبقى ال resting length هو ال intact length |
|
|
|
20 |
|
00:01:38,630 --> 00:01:44,790 |
|
العضلة سواء كانت of the non contracted and non |
|
|
|
21 |
|
00:01:44,790 --> 00:01:48,830 |
|
stretchedmuscle أما ال equilibrium فهي ال isolated |
|
|
|
22 |
|
00:01:48,830 --> 00:01:53,090 |
|
muscle أو uncontracted muscle لو عزلنا العضلة هذه |
|
|
|
23 |
|
00:01:53,090 --> 00:01:59,130 |
|
فهي حجمها بيقصر بيصغر أو طولها بيقصر حوالي عشرة في |
|
|
|
24 |
|
00:01:59,130 --> 00:02:04,990 |
|
المية طيب في عندنا ال .. ال variable التاني اللي |
|
|
|
25 |
|
00:02:04,990 --> 00:02:10,410 |
|
هو ال forceof tension يعني كلمة tension بنفضلها |
|
|
|
26 |
|
00:02:10,410 --> 00:02:14,850 |
|
أكتر من كلمة contraction ليش؟ لأن contraction كنت |
|
|
|
27 |
|
00:02:14,850 --> 00:02:19,770 |
|
كلمة كنتش معناها تقارب يعني هي a prefix بيعني أن |
|
|
|
28 |
|
00:02:19,770 --> 00:02:24,990 |
|
أشياء تقاربت من بعضها أو توصلت مع بعضها أما ال |
|
|
|
29 |
|
00:02:24,990 --> 00:02:30,150 |
|
tension فهي whether كان isometric أو concentric أو |
|
|
|
30 |
|
00:02:30,150 --> 00:02:34,450 |
|
eccentric contraction فكلمة tension بتعبر بتكون |
|
|
|
31 |
|
00:02:34,450 --> 00:02:40,690 |
|
معبرة أكتر tensionCan be applied to any type of |
|
|
|
32 |
|
00:02:40,690 --> 00:02:44,350 |
|
tension developed regardless ofwhether ال muscle |
|
|
|
33 |
|
00:02:44,350 --> 00:02:47,970 |
|
shortened or lengthened or remained the same |
|
|
|
34 |
|
00:02:47,970 --> 00:02:52,050 |
|
length سواء كان concentric contraction, eccentric |
|
|
|
35 |
|
00:02:52,050 --> 00:02:58,930 |
|
contraction or isometric contraction طبعا ال force |
|
|
|
36 |
|
00:02:58,930 --> 00:03:04,350 |
|
exerted by muscle is not only dependent upon ال |
|
|
|
37 |
|
00:03:04,350 --> 00:03:06,910 |
|
active process طبعا ال active process اللي هو |
|
|
|
38 |
|
00:03:06,910 --> 00:03:14,080 |
|
موجود اللي بيظهر مع ال contractile elementsأما في |
|
|
|
39 |
|
00:03:14,080 --> 00:03:18,840 |
|
عندنا passive tension بيصير على ال non contractile |
|
|
|
40 |
|
00:03:18,840 --> 00:03:23,360 |
|
مع ال non contractile element طبعا هنا ال muscle |
|
|
|
41 |
|
00:03:23,360 --> 00:03:28,520 |
|
فيها نوعين من ال connective أو some connective |
|
|
|
42 |
|
00:03:28,520 --> 00:03:33,250 |
|
tissue ال non contractile element اللي هي زيالـ |
|
|
|
43 |
|
00:03:33,250 --> 00:03:36,270 |
|
elastic band اللي موجودة إذا بتذكروا لما كنا |
|
|
|
44 |
|
00:03:36,270 --> 00:03:40,950 |
|
تكلمنا عن المكون المرة اللي فاتت وقلنا في عندنا ال |
|
|
|
45 |
|
00:03:40,950 --> 00:03:44,930 |
|
cross bridge اللي هو الأكتين والميوسين وفي عندنا |
|
|
|
46 |
|
00:03:44,930 --> 00:03:50,710 |
|
ال series وكانت parallel or series elastic |
|
|
|
47 |
|
00:03:50,710 --> 00:03:55,130 |
|
components هدولة اللي هما non-contractile elements |
|
|
|
48 |
|
00:03:55,490 --> 00:04:00,550 |
|
يبقى they behave as elastic band exert passive |
|
|
|
49 |
|
00:04:00,550 --> 00:04:04,170 |
|
force which combines with the active contribution |
|
|
|
50 |
|
00:04:04,170 --> 00:04:08,710 |
|
due cross bridging اللي بيصير في الميسين and أكتين |
|
|
|
51 |
|
00:04:08,710 --> 00:04:12,170 |
|
of the contractile elements in the muscle to |
|
|
|
52 |
|
00:04:12,170 --> 00:04:15,900 |
|
produce the total force exerted by the muscleطبعا |
|
|
|
53 |
|
00:04:15,900 --> 00:04:19,320 |
|
هي القوة اللى بتعملها العضلة هى عبارة عن force |
|
|
|
54 |
|
00:04:19,320 --> 00:04:24,240 |
|
بحثة القياس سبعتها لنيوتن زى ما احنا بنعرف من |
|
|
|
55 |
|
00:04:24,240 --> 00:04:29,420 |
|
الفصل اللى فاتطب ال tension produced by the muscle |
|
|
|
56 |
|
00:04:29,420 --> 00:04:32,300 |
|
contraction depends mechanically on the following |
|
|
|
57 |
|
00:04:32,300 --> 00:04:37,460 |
|
factor ال muscle length واحد منهم طول العضلة يبقى |
|
|
|
58 |
|
00:04:37,460 --> 00:04:42,060 |
|
العضلة هذه لما بتيجي بتعمل contraction حسب الطول |
|
|
|
59 |
|
00:04:42,060 --> 00:04:46,480 |
|
اللى بتكون فيه ساعة ما بيبدأ ال contractionفبكون |
|
|
|
60 |
|
00:04:46,480 --> 00:04:50,820 |
|
قداش في حاجة اسمها optimum link للعضلة العضلة لما |
|
|
|
61 |
|
00:04:50,820 --> 00:04:54,240 |
|
تكون إذا بتتذكروا زمان أول ما بدأنا في مادة ال |
|
|
|
62 |
|
00:04:54,240 --> 00:04:58,020 |
|
introduction قولنا العضلة بتشتغل أفضل شغلها في ال |
|
|
|
63 |
|
00:04:58,020 --> 00:05:02,350 |
|
intermediate course تبعهامعنى أنه لا بتشتغل منيح |
|
|
|
64 |
|
00:05:02,350 --> 00:05:06,290 |
|
إذا كانت في length position و لا بتشتغل منيح |
|
|
|
65 |
|
00:05:06,290 --> 00:05:10,890 |
|
العضلة إذا كانت في short position أفضل وضع بتشتغل |
|
|
|
66 |
|
00:05:10,890 --> 00:05:15,450 |
|
فيه العضلة و بيصير فيه development لإن ال tension |
|
|
|
67 |
|
00:05:15,450 --> 00:05:21,430 |
|
بيكون في ال optimum length بعت العضلة يبقى ال |
|
|
|
68 |
|
00:05:21,430 --> 00:05:25,590 |
|
relation between length and tension بdescribe هنا |
|
|
|
69 |
|
00:05:25,590 --> 00:05:31,000 |
|
على هذاال curve و زى ما احنا شايفين ال curve هنا |
|
|
|
70 |
|
00:05:31,000 --> 00:05:36,080 |
|
كاف بيبدأ هنا ال length كل ما قصرت العضلة بيبدأ ال |
|
|
|
71 |
|
00:05:36,080 --> 00:05:40,880 |
|
tension يصير في development و بعدين بيستقر و بعدين |
|
|
|
72 |
|
00:05:40,880 --> 00:05:46,250 |
|
بيعود بينزل تمام؟يبقى الـ active tension developed |
|
|
|
73 |
|
00:05:46,250 --> 00:05:49,250 |
|
by ال contractile elements of the muscle وهذا |
|
|
|
74 |
|
00:05:49,250 --> 00:05:53,170 |
|
معروف أن الأكتين والميسين بيصير فيهم cross |
|
|
|
75 |
|
00:05:53,170 --> 00:05:57,650 |
|
bridging و بيصير في عملية ال contraction اللي هو |
|
|
|
76 |
|
00:05:57,650 --> 00:06:02,650 |
|
عبارة عن تداخل خيوط الأكتين والميسين أو تبعدها في |
|
|
|
77 |
|
00:06:02,650 --> 00:06:06,760 |
|
حالة ال eccentric contraction كمانطب وقتش بصير |
|
|
|
78 |
|
00:06:06,760 --> 00:06:10,680 |
|
عندنا passive tension لما بتبدأ ال muscle develop |
|
|
|
79 |
|
00:06:10,680 --> 00:06:14,380 |
|
when the muscle is stretched beyond its resting، |
|
|
|
80 |
|
00:06:14,380 --> 00:06:18,920 |
|
ببدأ انشدها أكتر من ال resting position و ال non |
|
|
|
81 |
|
00:06:18,920 --> 00:06:23,800 |
|
contractile muscle بلي بيبدأ يصير فيه stretch، طيب |
|
|
|
82 |
|
00:06:23,970 --> 00:06:27,350 |
|
When the muscle contract both the active and the |
|
|
|
83 |
|
00:06:27,350 --> 00:06:30,610 |
|
passive tension هو بيعطينا ال total tension |
|
|
|
84 |
|
00:06:30,610 --> 00:06:34,930 |
|
exerted اللي احنا بنشوفه لما بنعمل ال contraction |
|
|
|
85 |
|
00:06:34,930 --> 00:06:41,170 |
|
ل العضلة سواء كان في concentric او eccentric work |
|
|
|
86 |
|
00:06:41,640 --> 00:06:47,520 |
|
الخطوة تشير إلى أنه عندما يتجسس المصدر بيوند موقعه |
|
|
|
87 |
|
00:06:47,520 --> 00:06:53,280 |
|
التجسسية الباسيف التنشن بيزيد و ال active tension |
|
|
|
88 |
|
00:06:53,280 --> 00:06:58,280 |
|
بيقل لأنه بيصير ال load أكتر على ال non |
|
|
|
89 |
|
00:06:58,280 --> 00:07:03,500 |
|
contractile element فبزيد عليها ال tension بتزيد |
|
|
|
90 |
|
00:07:03,500 --> 00:07:08,000 |
|
ال tension أما ال active tension فهو بيقلالـ |
|
|
|
91 |
|
00:07:08,000 --> 00:07:11,320 |
|
muscle can develop maximal tension at optimum |
|
|
|
92 |
|
00:07:11,320 --> 00:07:15,380 |
|
length because the thin and thick filaments of the |
|
|
|
93 |
|
00:07:15,380 --> 00:07:19,640 |
|
muscles are overlapped بيصير فيه تداخل على الـ |
|
|
|
94 |
|
00:07:19,640 --> 00:07:23,200 |
|
thin و ال thick filaments الميوسين و الأكتين |
|
|
|
95 |
|
00:07:23,200 --> 00:07:29,010 |
|
بيعطيني ال maximum number of cross bridgingيمكن أن |
|
|
|
96 |
|
00:07:29,010 --> 00:07:35,490 |
|
يتم تفعيلها بشكل عميق أو أقصر أكتر من أقصر أقصر |
|
|
|
97 |
|
00:07:35,490 --> 00:07:37,170 |
|

00:07:40,470 --> 00:07:47,280 |
|
أقصر أقصر أقصر أقصرless overlapping لـmyosin |
|
|
|
101 |
|
00:07:47,280 --> 00:07:50,520 |
|
والأكتين اللي هم الـthin and thick filaments of |
|
|
|
102 |
|
00:07:50,520 --> 00:07:54,580 |
|
the muscle وفي عندنا less number من ال cross |
|
|
|
103 |
|
00:07:54,580 --> 00:08:02,320 |
|
bridging عدد اللي هو ال myosin والأكتين بيقل طبعا |
|
|
|
104 |
|
00:08:04,310 --> 00:08:08,190 |
|
اللي هدى هى ال contractile elements اللى موجودة فى |
|
|
|
105 |
|
00:08:08,190 --> 00:08:15,230 |
|
العضلة نفسها طبعا فى عندنا هدى الظاهرة مابتبينش فى |
|
|
|
106 |
|
00:08:15,230 --> 00:08:19,730 |
|
ال mono-articular joint يعنى most one joint muscle |
|
|
|
107 |
|
00:08:19,730 --> 00:08:23,110 |
|
أو mono-articular muscle are not stretched enough |
|
|
|
108 |
|
00:08:23,110 --> 00:08:27,450 |
|
for ال passive tension حتى يظهر أو يبداله role هدى |
|
|
|
109 |
|
00:08:27,450 --> 00:08:31,070 |
|
بتصير موجودة أكتر فى ال two joint muscle أو اللى |
|
|
|
110 |
|
00:08:31,070 --> 00:08:35,400 |
|
بنسميه B-articular musclesليش؟ لأن هي بتعدي على |
|
|
|
111 |
|
00:08:35,400 --> 00:08:41,840 |
|
two joints و بتكون عادة هي أطول زي مثلا لو احنا |
|
|
|
112 |
|
00:08:41,840 --> 00:08:46,020 |
|
كلنا رفعنا إيدنا ال wrist لما بنعمل .. بتروح إيدنا |
|
|
|
113 |
|
00:08:46,020 --> 00:08:50,380 |
|
بال extension wrist extension فبنلاقي ال fingers |
|
|
|
114 |
|
00:08:50,380 --> 00:08:56,120 |
|
تلقائيا بتلاقيها بتتنى لو روحنا بإيدنا ب wrist |
|
|
|
115 |
|
00:08:56,120 --> 00:09:00,540 |
|
flexion بنلاقي ال fingers بيصير فيها extension و |
|
|
|
116 |
|
00:09:00,540 --> 00:09:04,060 |
|
هذا بيوضح لناعملية الـ passive و الـ active |
|
|
|
117 |
|
00:09:04,060 --> 00:09:10,680 |
|
tension طبعا هنا clinically the influence of pre |
|
|
|
118 |
|
00:09:10,680 --> 00:09:14,400 |
|
contraction stretch can be achieved وهذه ممكن |
|
|
|
119 |
|
00:09:14,400 --> 00:09:18,840 |
|
جزئية عشان تحسوا فيها بدها شوية عملية احنا عادة |
|
|
|
120 |
|
00:09:18,840 --> 00:09:22,660 |
|
بنسرق اذا انتوا درستوا ال BNF اذا بتذكروا كنا |
|
|
|
121 |
|
00:09:22,660 --> 00:09:25,440 |
|
بنقول اول ما بنبدأ ال contraction بنعمل sudden |
|
|
|
122 |
|
00:09:25,440 --> 00:09:29,680 |
|
stretch على ال muscle عشان نأوي ال contraction |
|
|
|
123 |
|
00:09:29,680 --> 00:09:35,970 |
|
وطول ما احنافي course of movement بنعمل stretching |
|
|
|
124 |
|
00:09:35,970 --> 00:09:41,250 |
|
للعضلة فبنحفظ ال energy اللي موجودة في العضلة انها |
|
|
|
125 |
|
00:09:41,250 --> 00:09:45,070 |
|
تزهر يبقى clinically the influence of contraction |
|
|
|
126 |
|
00:09:45,070 --> 00:09:49,370 |
|
stretch can be achieved by applying stretch before |
|
|
|
127 |
|
00:09:49,370 --> 00:09:53,230 |
|
muscle تعمل مع ال stretch reflex احنا contraction |
|
|
|
128 |
|
00:09:53,230 --> 00:09:56,390 |
|
or by lengthening the muscle during the course of |
|
|
|
129 |
|
00:09:56,390 --> 00:10:01,930 |
|
contractionIn this case, greater amount of tension |
|
|
|
130 |
|
00:10:01,930 --> 00:10:05,670 |
|
can be generated from the non-contractile elements |
|
|
|
131 |
|
00:10:05,670 --> 00:10:12,270 |
|
of the muscle طبعا ال muscle perform more work |
|
|
|
132 |
|
00:10:12,270 --> 00:10:15,710 |
|
when shortened immediately after being stretched |
|
|
|
133 |
|
00:10:15,710 --> 00:10:18,410 |
|
يعني احنا بنعمل concentric contraction بنبقى شدينا |
|
|
|
134 |
|
00:10:18,410 --> 00:10:22,990 |
|
العضلة و بعدين عملنا ال contraction فبيكون جهد على |
|
|
|
135 |
|
00:10:22,990 --> 00:10:28,380 |
|
العضلة أكتر و بتعطينا قوة أكترin the |
|
|
|
136 |
|
00:10:28,380 --> 00:10:33,700 |
|
concentrically contracted state than إذا كان صار |
|
|
|
137 |
|
00:10:33,700 --> 00:10:37,320 |
|
بعد shortening من isometric contraction يعني |
|
|
|
138 |
|
00:10:37,320 --> 00:10:40,540 |
|
العضلة يعني احنا خلينا نفترض ان ال biceps بتعمل |
|
|
|
139 |
|
00:10:40,540 --> 00:10:43,240 |
|
affliction احنا بدنا نعمل affliction against |
|
|
|
140 |
|
00:10:43,240 --> 00:10:49,360 |
|
resistance لمين لل biceps فاحنالو بدينا ال .. ال |
|
|
|
141 |
|
00:10:49,360 --> 00:10:53,280 |
|
.. ال concentric work هذا من stretch hand يعني من |
|
|
|
142 |
|
00:10:53,280 --> 00:10:57,400 |
|
full extension لقى القلب و عملنا stretch و قولنا |
|
|
|
143 |
|
00:10:57,400 --> 00:11:01,880 |
|
لأ المريض يلا go اعمل ال concentric contraction |
|
|
|
144 |
|
00:11:01,880 --> 00:11:04,860 |
|
بنحس حالنا ال contraction اللى developed أو ال |
|
|
|
145 |
|
00:11:04,860 --> 00:11:09,600 |
|
tension اللى developedأكتر بتحتاج العضلة لقوة كمان |
|
|
|
146 |
|
00:11:09,600 --> 00:11:12,760 |
|
على أنها تعمل و أكتر من أننا نبدأ من isometric |
|
|
|
147 |
|
00:11:12,760 --> 00:11:16,800 |
|
contraction و نكمل يعني في نص الطريق مثلا يكون |
|
|
|
148 |
|
00:11:16,800 --> 00:11:22,460 |
|
الشخص و نقوله اتني يبقى this is accounted for |
|
|
|
149 |
|
00:11:23,640 --> 00:11:26,860 |
|
باستخدام الطاقة الإلاستيكية المستخدمة في المجموعات |
|
|
|
150 |
|
00:11:26,860 --> 00:11:32,240 |
|

|
|

157 |
|
00:11:43,060 --> 00:11:46,960 |
|
relationship يعني علاقة بين القوة اللي بدها .. |
|
|
|
158 |
|
00:11:46,960 --> 00:11:50,780 |
|
اللي بدها تظهر علنا وبين ال time، احنا بنعرف انه |
|
|
|
159 |
|
00:11:50,780 --> 00:11:53,780 |
|
دايما ال eccentric contraction اللي هو ال .. ال |
|
|
|
160 |
|
00:11:53,780 --> 00:11:57,440 |
|
lengthening contraction بيعطيني energy أكتر و هو |
|
|
|
161 |
|
00:11:57,440 --> 00:12:02,420 |
|
أبطأ فبيعطيني قوة أكترطيب for generated by the |
|
|
|
162 |
|
00:12:02,420 --> 00:12:06,160 |
|
muscle is proportional force generated by the |
|
|
|
163 |
|
00:12:06,160 --> 00:12:09,560 |
|
muscle proportional to the contraction time يبقى |
|
|
|
164 |
|
00:12:09,560 --> 00:12:12,460 |
|
longer the time required for the muscle to |
|
|
|
165 |
|
00:12:12,460 --> 00:12:16,660 |
|
contract a greater the force developed up to the |
|
|
|
166 |
|
00:12:16,660 --> 00:12:19,860 |
|
point of maximal tension لحد ما يصير ال |
|
|
|
167 |
|
00:12:19,860 --> 00:12:24,360 |
|
contraction وصل آخره يبقى slower contraction في ال |
|
|
|
168 |
|
00:12:24,360 --> 00:12:29,100 |
|
eccentric زي ال eccentric workوهي تسبب في أكتر |
|
|
|
169 |
|
00:12:29,100 --> 00:12:36,460 |
|
إجراء قوة لأن الوقت المسمح لهذا الانتقال أطول من |
|
|
|
170 |
|
00:12:36,460 --> 00:12:44,560 |
|
الوضع الانتقالي للوضع الانتقالي الانتقالي للوضع |
|
|
|
171 |
|
00:12:44,560 --> 00:12:49,760 |
|
الانتقاليففي عندنا فرصة ليصير generation لها force |
|
|
|
172 |
|
00:12:49,760 --> 00:12:53,220 |
|
أكبر طبعاً there is a time delay between the |
|
|
|
173 |
|
00:12:53,220 --> 00:12:56,200 |
|
tension developed في ال active component |
|
|
|
174 |
|
00:12:56,200 --> 00:12:59,600 |
|
والdeveloped في ال non-contractile component طبعاً |
|
|
|
175 |
|
00:12:59,600 --> 00:13:03,960 |
|
في وقت ليصير ال twitch هذا ما بين ال contractile و |
|
|
|
176 |
|
00:13:03,960 --> 00:13:09,480 |
|
ال non-contractile elementsطبعا فيه هنا حاجة اسمها |
|
|
|
177 |
|
00:13:09,480 --> 00:13:15,220 |
|
fatigue، بنتعرض لها لما بيصير في عندنا يعني |
|
|
|
178 |
|
00:13:15,220 --> 00:13:19,520 |
|
contraction متكرر، طبعا احنا بنعرف انه عشان احنا |
|
|
|
179 |
|
00:13:19,520 --> 00:13:22,520 |
|
العضلة تبدأ contraction و تعمل release |
|
|
|
180 |
|
00:13:22,520 --> 00:13:28,340 |
|
للcontraction، في حاجة اسمها ATPالـ ATP له أدينوين |
|
|
|
181 |
|
00:13:28,340 --> 00:13:33,120 |
|
أدينوين الـ triphosphate هذا ال chemical substance |
|
|
|
182 |
|
00:13:33,120 --> 00:13:36,260 |
|
بتعملها ال synthesis العضلة عشان هي بتعمل ال |
|
|
|
183 |
|
00:13:36,260 --> 00:13:40,040 |
|
twitch بتخلي العضلة تعمل contraction عشان العضلة |
|
|
|
184 |
|
00:13:40,040 --> 00:13:43,040 |
|
تصير لها contraction بلزمها ATP وعشان تعمل release |
|
|
|
185 |
|
00:13:43,040 --> 00:13:48,060 |
|
لل contraction بلزمها ATP فهنا بتصير أن المشكلة |
|
|
|
186 |
|
00:13:48,060 --> 00:13:52,560 |
|
when if a muscle has an adequate supply of oxygen |
|
|
|
187 |
|
00:13:52,560 --> 00:13:57,880 |
|
and nutritionthat can be broken down عشان يصير هذه |
|
|
|
188 |
|
00:13:57,880 --> 00:14:02,240 |
|
عملية ايش metabolism او metabolic process بحتاج ال |
|
|
|
189 |
|
00:14:02,240 --> 00:14:06,320 |
|
oxygen و ال nutrients عشان يتحول هذه ال nutrients |
|
|
|
190 |
|
00:14:06,320 --> 00:14:11,920 |
|
ل ATP can be sustained a series مجموعة من ال low |
|
|
|
191 |
|
00:14:11,920 --> 00:14:18,020 |
|
frequency which is a response for a long time يعني |
|
|
|
192 |
|
00:14:18,020 --> 00:14:22,180 |
|
احنا نتكلم عن many activity او many contraction |
|
|
|
193 |
|
00:14:22,180 --> 00:14:28,300 |
|
على الterm أو على ال long time طب ال frequency |
|
|
|
194 |
|
00:14:28,300 --> 00:14:33,360 |
|
must be long enough to allow synthesis لل ATP يبقى |
|
|
|
195 |
|
00:14:33,360 --> 00:14:37,640 |
|
انا عشان انا يعني اذا بتذكروا احنا دايما تعليماتنا |
|
|
|
196 |
|
00:14:37,640 --> 00:14:40,680 |
|
لازم نعمل contraction و يبقى عندي وقت مضاعف لل |
|
|
|
197 |
|
00:14:40,680 --> 00:14:44,460 |
|
release لل contraction عشان نعطي فرصة لل ATP انه |
|
|
|
198 |
|
00:14:44,460 --> 00:14:50,220 |
|
يتعود يصيرله synthesis مرة تانيةThe frequency of |
|
|
|
199 |
|
00:14:50,220 --> 00:14:53,440 |
|
the stimulation increases more than the rate of |
|
|
|
200 |
|
00:14:53,440 --> 00:14:57,620 |
|
ATP replacement يعني لو صار فينا تكرار لعملية ال |
|
|
|
201 |
|
00:14:57,620 --> 00:14:59,800 |
|
contraction |
|
|
|
202 |
|
00:15:03,870 --> 00:15:08,590 |
|
عفوا فبصير ال ATP فش يعني .. يعني ممكن انه ي .. |
|
|
|
203 |
|
00:15:08,590 --> 00:15:11,910 |
|
يعني يقل لدرجة انه ينعدم ال ATP فبينعدم بعدها ال |
|
|
|
204 |
|
00:15:11,910 --> 00:15:15,090 |
|
contraction، بصير فيش قدرة، بصير drop in the |
|
|
|
205 |
|
00:15:15,090 --> 00:15:18,670 |
|
tension followed by a prolonged stimulation of |
|
|
|
206 |
|
00:15:18,670 --> 00:15:23,490 |
|
muscle بتسميه في هذه المرحلة اسمه muscle fatigue |
|
|
|
207 |
|
00:15:26,280 --> 00:15:29,240 |
|
الـ muscle fatigue هذه بتنتج نتيجة الـ metabolic |
|
|
|
208 |
|
00:15:29,240 --> 00:15:32,820 |
|
process اللي بيصيرله failure، بيصير مش قادر، هي |
|
|
|
209 |
|
00:15:32,820 --> 00:15:37,040 |
|
أساسا physiological mechanism بت .. عن طريق الـ |
|
|
|
210 |
|
00:15:37,040 --> 00:15:40,500 |
|
neurotransmitter أو neuromuscular system، هي اللي |
|
|
|
211 |
|
00:15:40,500 --> 00:15:44,400 |
|
بتساعد عملية ال contraction طب إذا فش ATP كفاية، |
|
|
|
212 |
|
00:15:44,400 --> 00:15:47,820 |
|
معناه إنه بيصير فيش عنا عضلة ماعندهاش القدرة على |
|
|
|
213 |
|
00:15:47,820 --> 00:15:52,680 |
|
إنها تستمر في ال contractionلما يكون ال exercise |
|
|
|
214 |
|
00:15:52,680 --> 00:15:57,180 |
|
when an exercising muscle begins to fatigue، a |
|
|
|
215 |
|
00:15:57,180 --> 00:16:00,640 |
|
rest period allows this muscle to resume its |
|
|
|
216 |
|
00:16:00,640 --> 00:16:04,120 |
|
normal performance level، وهذا اللي إحنا متعودين |
|
|
|
217 |
|
00:16:04,120 --> 00:16:07,960 |
|
فيه during exercising ل our patient or ourselves |
|
|
|
218 |
|
00:16:07,960 --> 00:16:11,960 |
|
as well، إنه إحنا بنعطي وقت لل rest قد الوقت أو |
|
|
|
219 |
|
00:16:11,960 --> 00:16:18,050 |
|
أكتر شوية من وقت ال contraction نفسهالقضاء اللي |
|
|
|
220 |
|
00:16:18,050 --> 00:16:24,450 |
|
يتطلبه يعتمد على الوقت والضرورة وانتصار التدخل حسب |
|
|
|
221 |
|
00:16:24,450 --> 00:16:27,070 |
|
التدخل اللي احنا عملناه طبعا نشوف ال example |
|
|
|
222 |
|
00:16:27,070 --> 00:16:31,470 |
|
البسيط هنا احنا بنقول انه كل مكان اللي احنا مثلا |
|
|
|
223 |
|
00:16:31,470 --> 00:16:37,990 |
|
حملنا يعني خلنا نقول box كبير او شنطة تقيلة تمام؟ |
|
|
|
224 |
|
00:16:37,990 --> 00:16:41,670 |
|
حملناها short duration فبنلاقي ال recovery كمان |
|
|
|
225 |
|
00:16:41,670 --> 00:16:45,950 |
|
بتكون بتاخد short duration as secondلو حملنا فترة |
|
|
|
226 |
|
00:16:45,950 --> 00:16:51,250 |
|
طويلة حملنا كيس مثلا ومشينا فيه مشوار طويل اه |
|
|
|
227 |
|
00:16:51,250 --> 00:16:56,150 |
|
فبنحتاج وقت اطول لانعاود ان نتخلص من ال fatigue |
|
|
|
228 |
|
00:16:56,150 --> 00:17:00,630 |
|
ability هذه اللي صارت عندنا يبقى ال muscle that is |
|
|
|
229 |
|
00:17:00,630 --> 00:17:05,250 |
|
rapidly fatigued by high intensity and short |
|
|
|
230 |
|
00:17:05,250 --> 00:17:08,690 |
|
duration exercise recovered after a rest of |
|
|
|
231 |
|
00:17:08,690 --> 00:17:12,130 |
|
seconds or minutes لكن لو كان في عندنا prolonged |
|
|
|
232 |
|
00:17:13,200 --> 00:17:16,980 |
|
أكتر فترة يبقى muscle that is slowly fatigued by |
|
|
|
233 |
|
00:17:16,980 --> 00:17:20,920 |
|
low intensity long duration exercise بتعطينا |
|
|
|
234 |
|
00:17:20,920 --> 00:17:26,400 |
|
بنحتاج لأكتر من 24 ساعة لإنه يصير في عنا recovery |
|
|
|
235 |
|
00:17:26,400 --> 00:17:31,440 |
|
لهذه العضلةنروح لموضوع شوية يعني خلّين .. يمكن أنا |
|
|
|
236 |
|
00:17:31,440 --> 00:17:35,500 |
|
بعتبره معقد لأنه ما هو سهل شرحه على .. بهذه |
|
|
|
237 |
|
00:17:35,500 --> 00:17:39,200 |
|
الطريقة، بدنا نحاول مع بعض نتعرف على ال Turk أو ال |
|
|
|
238 |
|
00:17:39,200 --> 00:17:42,980 |
|
moment اللي هو عزم الإزدواج اللي ممكن يكون موجود |
|
|
|
239 |
|
00:17:42,980 --> 00:17:48,320 |
|
على العضلة، ال Turk هو احنا بنعرفه العزمThe |
|
|
|
240 |
|
00:17:48,320 --> 00:17:51,640 |
|
ability of the muscle to rotate the segment around |
|
|
|
241 |
|
00:17:51,640 --> 00:17:54,920 |
|
the joint هلقت العضلة إيش وظيفتها؟ إنها تعمل |
|
|
|
242 |
|
00:17:54,920 --> 00:18:01,880 |
|
contraction إنها يا إما تزودلي ال .. تزود الزاوية |
|
|
|
243 |
|
00:18:01,880 --> 00:18:07,620 |
|
بين العظام أو تقرب الزاوية بين العظام يعني أنا |
|
|
|
244 |
|
00:18:07,620 --> 00:18:10,980 |
|
عشان أعمل muscle contraction في ال biceps أنا بلزم |
|
|
|
245 |
|
00:18:10,980 --> 00:18:15,450 |
|
إنه تصير في عندي decreasing للزاويةاللي بتروح في |
|
|
|
246 |
|
00:18:15,450 --> 00:18:19,310 |
|
اتجاه ال reflection و اللي بتبعد عن ال .. ال .. |
|
|
|
247 |
|
00:18:19,310 --> 00:18:24,390 |
|
الزاوية اللي في اتجاه ال extension يعني احنا بنقول |
|
|
|
248 |
|
00:18:24,390 --> 00:18:27,530 |
|
reflection مية و خمسة و عشرين درجة يعني زاوية ال |
|
|
|
249 |
|
00:18:27,530 --> 00:18:30,790 |
|
reflection هذه بتزيد هذه هو الحاجة احنا بدنا |
|
|
|
250 |
|
00:18:30,790 --> 00:18:34,650 |
|
نفهمها ال torque هو عبارة عن ايش؟ العزم هو عبارة |
|
|
|
251 |
|
00:18:34,650 --> 00:18:39,870 |
|
عن ال force ال force ضرب عزم الازدواج او ضرب ال |
|
|
|
252 |
|
00:18:39,870 --> 00:18:44,940 |
|
moment of arm اللي هو ذراع القوةطيب ال force قداش |
|
|
|
253 |
|
00:18:44,940 --> 00:18:49,400 |
|
فيه exerted force من العضلة و قداش فيه ذراع لهدي |
|
|
|
254 |
|
00:18:49,400 --> 00:18:53,280 |
|
القوة، قداش ال attachment هدا بيكون ابعيد زي ما |
|
|
|
255 |
|
00:18:53,280 --> 00:18:59,180 |
|
احنا شايفين هنا في ..الصورة هي عندنا المركز وهنا |
|
|
|
256 |
|
00:18:59,180 --> 00:19:03,240 |
|
ال .. هنا الحركة بدها تصير ال direction of |
|
|
|
257 |
|
00:19:03,240 --> 00:19:06,920 |
|
rotation وهنا ال force اللي بت .. بت .. بتساعدها |
|
|
|
258 |
|
00:19:06,920 --> 00:19:10,400 |
|
فهي المسافة عبارة عن إيه؟ القوة اللي ناتجة أو ال |
|
|
|
259 |
|
00:19:10,400 --> 00:19:13,200 |
|
torque اللي نازل عبارة عن ال force هنا مضروبة |
|
|
|
260 |
|
00:19:13,200 --> 00:19:17,000 |
|
بالمسافة هادي لإن هنا هي ال Falcon تبعنا وهي ال |
|
|
|
261 |
|
00:19:17,000 --> 00:19:21,700 |
|
torque arm اللي هو ذراع ال .. القوة اللي موجود |
|
|
|
262 |
|
00:19:21,700 --> 00:19:25,480 |
|
عندنا وهي القوة بتنضرب هادي في هادي فبيعطينا العزم |
|
|
|
263 |
|
00:19:25,480 --> 00:19:31,580 |
|
الإزدواج اللي احنابنبتغي أو القوة اللي سايرة الـ |
|
|
|
264 |
|
00:19:31,580 --> 00:19:34,780 |
|
Torque Angle Curve طبعاً في عنا نوع تلت أنواع في |
|
|
|
265 |
|
00:19:34,780 --> 00:19:37,940 |
|
عنا ال Ascending Relationship وعنا ال Descending |
|
|
|
266 |
|
00:19:37,940 --> 00:19:41,980 |
|
Relationship وفي عنا ال Ascending and Descending |
|
|
|
267 |
|
00:19:41,980 --> 00:19:47,640 |
|
مع بعض يعني بتبدأ في أنها بزيد العزم أو بعدين بيقل |
|
|
|
268 |
|
00:19:47,640 --> 00:19:51,640 |
|
طبعا دي إعلانقة بين ال Torque و بين ال Joint Angle |
|
|
|
269 |
|
00:19:51,640 --> 00:19:57,750 |
|
اللي بدها تحصل نتيجة القوة العضليةأو الحركة اللى |
|
|
|
270 |
|
00:19:57,750 --> 00:20:02,890 |
|
قامت فيها العضلة الـ Ascending relation الـ joint |
|
|
|
271 |
|
00:20:02,890 --> 00:20:07,490 |
|
كل ما بتزيد ال joint ankle بيزيد ال torque يبقى in |
|
|
|
272 |
|
00:20:07,490 --> 00:20:10,510 |
|
this case زى ال knee flexor فيه أو ال hip |
|
|
|
273 |
|
00:20:10,510 --> 00:20:16,110 |
|
adductors عضلات طويلة هذه فهى بيكون العزم تبعها كل |
|
|
|
274 |
|
00:20:16,110 --> 00:20:21,010 |
|
ما زادت الزاوية كل ما زاد العزم تبعها أو ال torque |
|
|
|
275 |
|
00:20:21,010 --> 00:20:25,300 |
|
تبعهاالـ descending لأ بتكون عضلات عنا قصيرة شوية |
|
|
|
276 |
|
00:20:25,300 --> 00:20:30,020 |
|
يبقى as the joint angle increase ال torque بصير |
|
|
|
277 |
|
00:20:30,020 --> 00:20:34,840 |
|
فيه decrease يعني بتزيد ال .. ال .. بتكون علاقة |
|
|
|
278 |
|
00:20:34,840 --> 00:20:41,730 |
|
عكسيةزي الـ hip abductors زي الـ gluteus medius و |
|
|
|
279 |
|
00:20:41,730 --> 00:20:44,870 |
|
ال internal .. the internal torque of the muscle |
|

is the greatest at the frontal plane، ال angle |
|
|
|
281 |
|
00:20:48,150 --> 00:20:53,130 |
|
بتصير على ال minus عشرة degree towards abduction |
|
|
|
282 |
|
00:20:55,870 --> 00:20:59,230 |
|
هذا الرسم بيوضح كيف العلاقة لما تكون ascending |
|
|
|
283 |
|
00:20:59,230 --> 00:21:03,690 |
|
بتزيد و بعدين بتعود بتقل هنا العلاقة لما تكون |
|
|
|
284 |
|
00:21:03,690 --> 00:21:08,250 |
|
descending و هنا العلاقة لما بتكون ascending بتكون |
|
|
|
285 |
|
00:21:08,250 --> 00:21:12,370 |
|
شوفوا فيه زيادة في ال angle و كمان زيادة في ال |

هنا إيش بنستفيد من هذا الكلام؟ بنستفيد إنه في بعض |
|
|
|
303 |
|
00:22:25,360 --> 00:22:29,960 |
|
الحالات عندنا أحيانا بيكون فيه قلم زي القلم بالـ |

|
|
|
311 |
|
00:23:09,380 --> 00:23:13,400 |
|
في عندنا مشكلة إن هي عضلة صغيرة و ال attachment |
|
|
|
312 |
|
00:23:13,400 --> 00:23:17,540 |
|
تبعها على greater retro counter و لما يكون العزم |
|
|
|
313 |
|
00:23:17,540 --> 00:23:21,400 |
|
هنا قليل بتحتاج .. احنا كل ما زاد دراعي القوة كل |
|
|
|
314 |
|
00:23:21,400 --> 00:23:26,000 |
|
ما نضرب فيه القوة محتاج force من العضلة عشان تعمل |
|
|
|
315 |
|
00:23:26,000 --> 00:23:31,580 |
|
ال contraction أقل لأنها بتنضرب بال movement arm |
|
|
|
316 |
|
00:23:31,580 --> 00:23:36,710 |
|
فبتزيد القوة فهيقل الوجع فهم بيلعبوا بيحركوافي الـ |

|
|
|
318 |
|
00:23:40,110 --> 00:23:44,110 |
|
decreased hip abductor force can reduce the force |
|
|

00:23:44,110 --> 00:23:47,650 |
|
generated across the unstable or painful hip joint |
|
|

320 |
|
00:23:47,650 --> 00:23:51,510 |
|
which considered a means of protection of the |

00:24:00,050 --> 00:24:04,890 |
|
ركبته مباشرة و بيصير فيه fracture في البتلة |

|
00:24:24,020 --> 00:24:30,700 |
|
knee jointنروح للنقطة الخامسة اللي هي ال velocity |
|
|
|
329 |
|
00:24:30,700 --> 00:24:34,540 |
|
أو السرعة، السرعة انتوا عارفين احنا measured by |
|
|
|
330 |
|
00:24:34,540 --> 00:24:39,980 |
|
centimeter per secondهذه السرعة ال muscle defined |
|
|
|
331 |
|
00:24:39,980 --> 00:24:43,260 |
|
ال velocity of the muscle is defined as ال rate of |
|
|
|
332 |
|
00:24:43,260 --> 00:24:46,880 |
|
changing in muscle length كدهش بيصير ال rate |
|
|
|
333 |
|
00:24:46,880 --> 00:24:51,240 |
|
لتغيير ال length of the muscle طبعا ال force |
|

|
|
|
335 |
|
00:24:54,680 --> 00:24:57,120 |
|
force و ما بين ال length في ال isometric |
|
|
|
336 |
|
00:24:57,120 --> 00:25:03,080 |
|
contraction بتكون صفرzero velocity ليش لأنه لا في |
|
|
|
337 |
|
00:25:03,080 --> 00:25:08,380 |
|
عندنا تغيير في الطول ولا في عندنا و العزم بيصير |
|
|
|
338 |
|
00:25:08,380 --> 00:25:15,510 |

|
|
|
341 |
|
00:25:23,790 --> 00:25:26,630 |
|
السرعة بيقل ال torque وهذا اللي احنا بنشوفه في ال |
|
|
|
342 |
|
00:25:26,630 --> 00:25:30,650 |
|
concentric contraction لما يكون مافيش عندنا حركة و |
|
|
|
343 |
|
00:25:30,650 --> 00:25:34,330 |
|
مافيش عندنا .. مافيش فيه سرعة في ال at zero |
|
|
|
344 |
|
00:25:34,330 --> 00:25:37,010 |
|
velocity هنا في ال contraction ال muscle can |
|
|
|
345 |
|
00:25:37,010 --> 00:25:43,190 |
|
produce high torque زي ما احنا شايفينه هنافي هذه |
|
|
|
346 |
|
00:25:43,190 --> 00:25:49,510 |
|
النقطة في ال isometric contraction فلده في ال |
|
|
|
347 |
|
00:25:49,510 --> 00:25:55,350 |
|
lengthening هتختلف الأمور يبقى at high velocity or |
|
|
|
348 |
|
00:25:55,350 --> 00:25:59,330 |
|
in case of concentric contraction ال muscle |
|
|
|
349 |
|
00:25:59,330 --> 00:26:04,650 |
|
produces lower torque أقل torque than in case of |
|
|
|
350 |
|
00:26:04,650 --> 00:26:07,910 |
|
isometric contraction |
|
|
|
351 |
|
00:26:10,790 --> 00:26:15,550 |
|
إذا زرع السرعات تزداد ترق المضمون في المضمون تتخلص |
|
|
|
352 |
|
00:26:15,550 --> 00:26:22,970 |
|
حتى يوصل إلى أقل في أقل سرعات وبتوصل السفر يبقى في |
|
|
|
353 |
|
00:26:22,970 --> 00:26:28,990 |
|
أقل سرعات أو في حالة مضمون أساسي المضمون يتخلص |
|
|
|
354 |
|
00:26:28,990 --> 00:26:33,390 |
|
المضمون من ترق أعلىthan in case of isometric |
|
|
|
355 |
|
00:26:33,390 --> 00:26:37,630 |
|
contraction إذا ال velocity of the contraction هنا |
|
|
|
356 |
|
00:26:37,630 --> 00:26:44,690 |
|
بتزيد ال torque بتقل يبقى ال torque بيزيد لحد ما |
|
|
|
357 |
|
00:26:44,690 --> 00:26:48,490 |
|
ال torque بصير maximum في ال minimum velocity |
|
|
|
358 |
|
00:26:48,490 --> 00:26:52,750 |
|
وإحنا عارفين إنه اللي إحنا بنعمل exertion لقوة |
|
|
|
359 |
|
00:26:52,750 --> 00:26:56,070 |
|
أكبر في ال eccentric contraction than ال |
|
|
|
360 |
|
00:26:56,070 --> 00:27:05,250 |
|
concentric contraction هي أنه هناالتيرب بيزيد نروح |
|
|
|
361 |
|
00:27:05,250 --> 00:27:09,610 |

time, contraction, velocityكيف بنعبر عنها بال |
|
|
|
365 |
|
00:27:24,160 --> 00:27:29,960 |
|
equation ال power بتساوي ال work على ال time يبقى |
|
|
|
366 |
|
00:27:29,960 --> 00:27:34,140 |
|
ال work output that is a muscle must be able to |
|
|
|
367 |
|
00:27:34,140 --> 00:27:39,940 |
|
contract forcibly and with high velocity to have a |
|
|
|
368 |
|
00:27:39,940 --> 00:27:45,870 |
|
higher power outputيعني احنا عادة بنقس قوة الأشياء |
|
|
|
369 |
|
00:27:45,870 --> 00:27:51,270 |
|
بقداش قدرتها على العمل، قداش ال output تبعها، يبقى |
|
|
|
370 |
|
00:27:51,270 --> 00:27:58,580 |
|
ال work تعنيلي قداش ممكن تعمل work على ال timeطب |
|
|
|
371 |
|
00:27:58,580 --> 00:28:01,780 |
|
ال work لحاله بنعبّر عليه بال equation ال force |
|
|
|
372 |
|
00:28:01,780 --> 00:28:06,280 |
|
ضرب ال distance طيب ال power بتساوي ال force ضرب |
|
|
|
373 |
|
00:28:06,280 --> 00:28:08,900 |
|
ال distance على ال time ال distance على ال time |
|
|
|
374 |
|
00:28:08,900 --> 00:28:12,320 |
|
هادي عبارة عن ال velocity فبالتالي ال power بتصير |
|
|
|
375 |
|
00:28:12,320 --> 00:28:16,730 |
|
بتساوي ال force ضرب ال velocityفينا نوعين من ال |
|
|
|
376 |
|
00:28:16,730 --> 00:28:20,210 |
|
work ممكن تعملهم العضلة، ال positive work و ال |
|
|
|
377 |
|
00:28:20,210 --> 00:28:23,750 |
|
negative work، طب ال positive work هو عبارة عن |
|
|
|
378 |
|
00:28:23,750 --> 00:28:29,490 |
|
ايش؟ هو contract .. contraction against ال load |
|
|
|
379 |
|
00:28:30,510 --> 00:28:33,090 |
|
يعني أنا بكون في عينة concentric أنا حاملة بإيدي |
|
|
|
380 |
|
00:28:33,090 --> 00:28:37,370 |
|
مثلا dumbbell و بعمل biceps concentric contraction |
|
|
|
381 |
|
00:28:37,370 --> 00:28:41,230 |
|
هي ال retina of positive work بنسميها power |
|
|
|
382 |
|
00:28:41,230 --> 00:28:46,680 |
|
production يعني أنا بقوي العضلة طبعا؟أما ال |
|
|
|
383 |
|
00:28:46,680 --> 00:28:49,080 |
|
negative work بروح فيه عن طريق ال eccentric |
|
|
|
384 |
|
00:28:49,080 --> 00:28:52,480 |
|
contraction يعني انا suppose اني انا حاملة بإيدي |
|
|
|
385 |
|
00:28:52,480 --> 00:28:58,100 |
|
عشرة كيلو و قاعدة بحاول أنزلهم شوية شوية على ال .. |
|
|
|
386 |
|
00:28:58,100 --> 00:29:01,500 |
|
على جنبي يعني انا من biceps contraction يعني بتكون |
|
|
|
387 |
|
00:29:01,500 --> 00:29:04,980 |
|
انا ماسكة ب friction of the elbow و قاعدة بنزل هنا |
|
|
|
388 |
|
00:29:04,980 --> 00:29:08,860 |
|
بتصير الحركة slowly و بصير فيها storage لل energy |
|
|
|
389 |
|
00:29:08,860 --> 00:29:12,260 |
|
لإن أنا بعمل eccentric work فبتسمى power |
|
|
|
390 |
|
00:29:12,260 --> 00:29:18,710 |
|
absorption يبقى ال negative workطبعا during the |
|
|
|
391 |
|
00:29:18,710 --> 00:29:22,430 |
|
isometric contraction ال muscle experience |
|
|
|
392 |
|
00:29:22,430 --> 00:29:29,230 |
|
metabolic work بيصير فيها يعني تجمع لخلينا نقول |
|
|
|
393 |
|
00:29:29,230 --> 00:29:34,830 |
|
الدم و ال nutrition because the activation of the |
|
|
|
394 |
|
00:29:34,830 --> 00:29:39,020 |
|
muscle involved expenditure to energy ATPbut no |
|
|
|
395 |
|
00:29:39,020 --> 00:29:42,560 |
|
mechanical work is produced لأنه مافيش حركة |
|
|
|
396 |
|
00:29:42,560 --> 00:29:46,080 |
|
mechanical work يعني فيش حركة يعني صح احنا بنعمل |
|
|
|
397 |
|
00:29:46,080 --> 00:29:50,160 |
|
isometric contraction ل .. اه لكن الحركة مافي .. |
|
|
|
398 |
|
00:29:50,160 --> 00:29:54,320 |
|
مافي حركة يعني ال ATP يعني العضلة ال ATP هنا بيصير |
|
|
|
399 |
|
00:29:54,320 --> 00:30:00,020 |
|
في .. يعني بيتعرض لإنه بدنا ATP لكن حقيقي مافيش |
|
|
|
400 |
|
00:30:00,020 --> 00:30:00,980 |
|
عندنا حركة |
|
|
|
401 |
|
00:30:04,640 --> 00:30:09,040 |
|
الروح لأخر إشي معناه اللى هى ال muscle length هو |
|
|
|
402 |
|
00:30:09,040 --> 00:30:14,680 |
|
كيف احنا يعني بأثر ال muscle sorry ال muscle |
|
|
|
403 |
|
00:30:14,680 --> 00:30:18,080 |
|
strength كيف احنا بنعمل improving لل muscle |
|
|
|
404 |
|
00:30:18,080 --> 00:30:21,340 |
|
strength وكيف احنا بنعرف أن هاد العضلة ممكن تكون |
|
|
|
405 |
|
00:30:21,340 --> 00:30:25,060 |
|
قوية أو لأ عندنا ال muscle strength is the maximum |
|
|
|
406 |
|
00:30:25,060 --> 00:30:30,060 |
|
amount of force exerted by the muscle قداش قدرة |
|
|
|
407 |
|
00:30:30,060 --> 00:30:36,030 |
|
العضلةأكتر إشي ممكن تتحمله العضلة، يعني ال muscle |
|
|
|
408 |
|
00:30:36,030 --> 00:30:39,570 |
|
length بتاعي أنا أديش بقدر أحمل خمسة كيلو، عشرة |
|
|
|
409 |
|
00:30:39,570 --> 00:30:43,770 |
|
كيلو، خمستاشر كيلو بال biceps، هذه اسمها muscle |
|
|
|
410 |
|
00:30:43,770 --> 00:30:46,770 |
|
strength هو directly proportional to the |
|
|
|
411 |
|
00:30:46,770 --> 00:30:50,270 |
|
physiological across section due to physiological |
|
|
|
412 |
|
00:30:50,270 --> 00:30:54,140 |
|
hypertrophicityزي عضلة الـ Quadriceps احنا بنشوفها |
|
|
|
413 |
|
00:30:54,140 --> 00:30:58,000 |
|
عضلة .. هي عضلة ربعية و عضلة كتير الـ diameter |
|
|
|
414 |
|
00:30:58,000 --> 00:31:01,960 |
|
تبعها كبير يعني الـ hypertrophicity هنا increase |
|
|
|
415 |
|
00:31:01,960 --> 00:31:05,920 |
|
ال muscle size بتزود ال muscle size و it's usually |
|
|
|
416 |
|
00:31:05,920 --> 00:31:11,940 |
|
additional 30 ل 60% بزيد من بال .. عن طريق اللي هو |
|
|
|
417 |
|
00:31:11,940 --> 00:31:15,940 |
|
من 30 ل 60% عن طريق ال exercise أو التمرين اللي |
|
|
|
418 |
|
00:31:15,940 --> 00:31:19,720 |
|
بيصير فيه هناhypertrophicity للـ fibers of the |
|
|
|
419 |
|
00:31:19,720 --> 00:31:22,400 |
|
muscle يعني هو عددها مش هو اللي بيزيد هي بيصير |
|
|
|
420 |
|
00:31:22,400 --> 00:31:26,600 |
|
فيها trophicity أكتر طبعا هنا العضلات العضلات |
|
|
|
421 |
|
00:31:26,600 --> 00:31:30,260 |
|
الأوية و الكبيرة لما بتصير بتعمل activity activity |
|
|
|
422 |
|
00:31:30,260 --> 00:31:35,360 |
|
مابتعملش activation لكل ال fibers تبعتها يبقى the |
|
|
|
423 |
|
00:31:35,360 --> 00:31:38,920 |
|
stronger muscle are not acting wholly but part act |
|
|
|
424 |
|
00:31:38,920 --> 00:31:42,520 |
|
and other part are rest عشان هيك ده this permit |
|
|
|
425 |
|
00:31:42,520 --> 00:31:45,960 |
|
early recovery and allow individual to do more for |
|
|
|
426 |
|
00:31:45,960 --> 00:31:49,230 |
|
longer periodof time العادلة بتكون كبيرة فبستخدم |
|
|
|
427 |
|
00:31:49,230 --> 00:31:55,090 |
|
جزء من ال fibers و بتخليه جزء و مبدل ما بينهم طبعا |
|
|
|
428 |
|
00:31:55,090 --> 00:31:57,990 |
|
نتكلم عن حاجة اسمها muscle endurance اللي احنا |
|
|
|
429 |
|
00:31:57,990 --> 00:32:00,770 |
|
صارنا في عندنا muscle power و في عندنا muscle |
|
|
|
430 |
|
00:32:00,770 --> 00:32:06,570 |
|
strength و في عندنا muscle endurance طبعا ال |
|
|
|
431 |
|
00:32:06,570 --> 00:32:11,760 |
|
strength قداش قدرتناإن نشيل يعني عشرة أو خمستاشر |
|
|
|
432 |
|
00:32:11,760 --> 00:32:16,740 |
|
كيلو أما ال endurance قداش إحنا فينا نستمر و إحنا |
|
|
|
433 |
|
00:32:16,740 --> 00:32:19,940 |
|
بنعمل هذا التمرين يعني مش شرط أنا أحمل خمستاشر |
|
|
|
434 |
|
00:32:19,940 --> 00:32:23,460 |
|
كيلو ممكن أحمل خمسة كيلو و أستمر لمدة ساعة و أنا |
|
|
|
435 |
|
00:32:23,460 --> 00:32:26,900 |
|
بمرر إيدي يبقى هي the ability of the muscle to |
|
|
|
436 |
|
00:32:26,900 --> 00:32:31,620 |
|
exert force repeatedly over a period of time بدي |
|
|
|
437 |
|
00:32:31,620 --> 00:32:36,820 |
|
وقت أنا عشان أعمل الحركة هذهالـ endurance training |
|
|
|
438 |
|
00:32:36,820 --> 00:32:41,300 |
|
involve enhancement of muscle energy supply rather |
|
|
|
439 |
|
00:32:41,300 --> 00:32:45,000 |
|
than its size يعني أنا باهتم هنا بال endurance أنا |
|
|
|
440 |
|
00:32:45,000 --> 00:32:48,540 |
|
بدي يكون ال energy supply زي ال ATP أكتر ما أنا |
|
|
|
441 |
|
00:32:48,540 --> 00:32:52,640 |
|
بدي حجم العضلة لإنه الحجم هذا بيعطيني strength لكن |
|
|
|
442 |
|
00:32:52,640 --> 00:32:56,380 |
|
أنا هنا معنية بالطاقة أنا كيف بدي أقدر أستمر في |
|
|
|
443 |
|
00:32:56,380 --> 00:33:00,490 |
|
long term أو long period of exercisingيبقى |
|
|
|
444 |
|
00:33:00,490 --> 00:33:05,510 |
|
endurance is related to increase in muscle |
|
|
|
445 |
|
00:33:05,510 --> 00:33:09,430 |
|
myoglobin concentration capillary number and |
|
|
|
446 |
|
00:33:09,430 --> 00:33:15,250 |
|
mitochondrial size and number هنا لإن أنا هنا |
|
|
|
447 |
|
00:33:15,250 --> 00:33:19,410 |
|
معنية بال metabolism أكتر ما أنا معنية بال |
|
|
|
448 |
|
00:33:19,410 --> 00:33:24,580 |
|
strength أو بالحجميبقى trained muscle is not easy |
|
|
|
449 |
|
00:33:24,580 --> 00:33:28,340 |
|
to fatigue because it utilize more effective |
|
|
|
450 |
|
00:33:28,340 --> 00:33:33,920 |
|
metabolic reaction at the muscle is oxygenated |
|
|
|
451 |
|
00:33:33,920 --> 00:33:39,040 |
|
through the conditions of cardiovascular and |
|
|
|
452 |
|
00:33:39,040 --> 00:33:42,460 |
|
respiratory system، ليش؟ لأن ال cardiovascular and |
|
|
|
453 |
|
00:33:42,460 --> 00:33:46,480 |
|
respiratory systemهما مصادر الـ Oxygen اللي بده |
|
|
|
454 |
|
00:33:46,480 --> 00:33:50,860 |
|
ييجي يساعد في عملية الـ metabolism عن طريق الدم |
|
|
|
455 |
|
00:33:50,860 --> 00:33:56,460 |
|
اللي بيرسله القلب لأجزاء الجسم ومنها العضلة طبعا |
|
|
|
456 |
|
00:33:56,460 --> 00:34:01,310 |
|
ال elasticity اشي كتير مهمهو عبارة عن ال capacity |
|
|
|
457 |
|
00:34:01,310 --> 00:34:04,950 |
|
to lengthen the muscle sufficiently to move the |
|
|
|
458 |
|
00:34:04,950 --> 00:34:08,030 |
|
joint throughout its range of motion، قداش احنا |
|
|
|
459 |
|
00:34:08,030 --> 00:34:12,330 |
|
ممكن احنا نفرض هذه العضلة و تكون عندها قدرة على |
|
|
|
460 |
|
00:34:12,330 --> 00:34:20,010 |
|
الرجوع لما قبل ال stretch أو ال lengtheningيبقى |
|
|
|
461 |
|
00:34:20,010 --> 00:34:23,450 |
|
elasticity can be improved by decreasing |
|
|
|
462 |
|
00:34:23,450 --> 00:34:27,290 |
|
resistance of thigh musc tight muscle using static |
|
|
|
463 |
|
00:34:27,290 --> 00:34:31,430 |
|
or dynamic stretch techniques or by increasing the |
|
|
|
464 |
|
00:34:31,430 --> 00:34:34,130 |
|
strength of the antagonist يعني يا إما أنا بشد |
|
|
|
465 |
|
00:34:34,130 --> 00:34:37,930 |
|
العضلاء يا إما بأول عضلاء اللي على قبلها عشان أنا |
|
|
|
466 |
|
00:34:37,930 --> 00:34:42,480 |
|
أقدر أزود ال elasticity تبعتهاas the muscle is |
|
|
|
467 |
|
00:34:42,480 --> 00:34:47,500 |
|
viscoelastic، الـ elastic properity permits spring |
|
|
|
468 |
|
00:34:47,500 --> 00:34:51,220 |
|
-like behavior اللي بيخلّي العضلة ترجع لل original |
|
|
|
469 |
|
00:34:51,220 --> 00:34:56,060 |
|
link بعد ما تكون صار لها stretching، طبعا |
|
|
|
470 |
|
00:34:56,060 --> 00:34:58,960 |
|
الviscosity أو الviscosity properity بتخلي حاجة |
|
|
|
471 |
|
00:34:58,960 --> 00:35:02,680 |
|
اسمها plasticityto permanent or permanent |
|
|
|
472 |
|
00:35:02,680 --> 00:35:07,060 |
|
deformation قبل هيك حكينا عن إيش الفرق بين ال |
|
|
|
473 |
|
00:35:07,060 --> 00:35:11,260 |
|
plasticity و ال elasticity ال elasticity هي أنه |
|
|
|
474 |
|
00:35:11,260 --> 00:35:15,480 |
|
يرجع الأشي إلى ما قبل ال tension أو ما قبل ال |
|
|
|
475 |
|
00:35:15,480 --> 00:35:20,500 |
|
stretchingيعني مقاطعة إحنا شدناها رجعت لوضعها فدي |
|
|
|
476 |
|
00:35:20,500 --> 00:35:24,180 |
|
حاجة أسمها elasticity شدناها كتير مثلا طول الليل |
|
|
|
477 |
|
00:35:24,180 --> 00:35:28,640 |
|
أو لفترة طويلة أو استخدمناها كتير فهي بتروح لحاجة |
|
|
|
478 |
|
00:35:28,640 --> 00:35:32,200 |
|
أسمها plasticity بيصير فيها permanent deformation |
|
|
|
479 |
|
00:35:32,200 --> 00:35:37,600 |
|
وبتغير ال length تبعهابعدين عندنا الرقم أربع اللي |
|
|
|
480 |
|
00:35:37,600 --> 00:35:43,420 |
|
هو ال increase muscle efficiency طبعا calculated |
|
|
|
481 |
|
00:35:43,420 --> 00:35:47,860 |
|
as the percent of energy input that is converted |
|
|
|
482 |
|
00:35:47,860 --> 00:35:52,320 |
|
into work instead of heat قداش بيصير في عندنا |
|
|
|
483 |
|
00:35:52,320 --> 00:35:57,960 |
|
عملية metabolism و energy موجودة بتساعد على عملية |
|
|
|
484 |
|
00:35:57,960 --> 00:36:04,120 |
|
اللي هي ال work القوة ال efficiency أو القدرة |
|
|
|
485 |
|
00:36:04,120 --> 00:36:10,350 |
|
هنسميها القدرةالـ efficiency of the muscle is less |
|
|
|
486 |
|
00:36:10,350 --> 00:36:16,030 |
|
than 20 to 25% the reason for this law efficiency |
|
|
|
487 |
|
00:36:16,030 --> 00:36:20,030 |
|
is that about half of the energy في ال food stuffs |
|
|
|
488 |
|
00:36:20,030 --> 00:36:24,270 |
|
lost during ال formation of ال ATP لأن هذا ال |
|
|
|
489 |
|
00:36:24,270 --> 00:36:28,310 |
|
energy احنا بنحتاجه عشان عملية ال metabolismاللي |
|
|
|
490 |
|
00:36:28,310 --> 00:36:32,610 |
|
بتساعد على ال ATP formation عشان تعملي contraction |
|
|
|
491 |
|
00:36:32,610 --> 00:36:36,910 |
|
and release of the muscle بال exercise ال maximum |
|
|
|
492 |
|
00:36:36,910 --> 00:36:40,370 |
|
efficiency of the muscle developed especially when |
|
|
|
493 |
|
00:36:40,370 --> 00:36:44,970 |
|
the velocity of contraction about 30% لما بيكون ال |
|
|
|
494 |
|
00:36:44,970 --> 00:36:53,930 |
|
contraction مش كتير أوي أو سريعالتجارب أضافت قوة |
|
|
|
495 |
|
00:36:53,930 --> 00:36:58,910 |
|
أسهل للتعب بقليل من التعب، ونعرف أنه كل ما تمرنت |
|
|
|
496 |
|
00:36:58,910 --> 00:37:03,870 |
|
العضلة، كل ما كان في عندنا قدرة على تحميل التعب |
|
|
|
497 |
|
00:37:03,870 --> 00:37:09,050 |
|
لفترة طويلة، تتطور، طبعا في هنا الـcircle، |
|
|
|
498 |
|
00:37:09,050 --> 00:37:15,070 |
|
الـcircle لما تصبح ثقر، تزداد عضلات التواصل في عدد |
|
|
|
499 |
|
00:37:15,070 --> 00:37:20,060 |
|
بتصير فيهابتتجدد و بتتحسن there is also greater |
|
|
|
500 |
|
00:37:20,060 --> 00:37:24,260 |
|
amount of glycogen needed to supply the trend |
|
|
|
501 |
|
00:37:24,260 --> 00:37:27,860 |
|
muscle within the muscle itself عشان تساعد في |
|
|
|
502 |
|
00:37:27,860 --> 00:37:31,400 |
|
عمليات ال metabolism نروح لحاجة اسمها muscle |
|
|
|
503 |
|
00:37:31,400 --> 00:37:34,740 |
|
injury، في عندنا أربعة من ال muscle injury مش |
|
|
|
504 |
|
00:37:34,740 --> 00:37:37,860 |
|
عارفة هنا ناقصة واحدة، عندنا ال acute muscle |
|
|
|
505 |
|
00:37:37,860 --> 00:37:42,500 |
|
strain و ال muscle contusion و ال exercise induced |
|
|
|
506 |
|
00:37:42,500 --> 00:37:47,210 |
|
injury و الرابعة هي ال crampsالـ acute muscle |
|
|
|
507 |
|
00:37:47,210 --> 00:37:54,030 |
|
strain بيصير نتيجة result from overstretch of |
|
|
|
508 |
|
00:37:54,030 --> 00:37:59,830 |
|
passive muscle or dynamically overloaded and |
|
|
|
509 |
|
00:37:59,830 --> 00:38:03,390 |
|
active muscle سواء كانت concentrically or |
|
|
|
510 |
|
00:38:03,390 --> 00:38:06,130 |
|
eccentrically يعني أنتوا عارفين ال muscle strain |
|
|
|
511 |
|
00:38:06,130 --> 00:38:10,290 |
|
بيصير فيه شد مفاجئفي ال fibers تبع العضلة ممكن |
|
|
|
512 |
|
00:38:10,290 --> 00:38:16,930 |
|
انها تنقطع او ممكن انها تنشد و .. و تتمزق تنزق جزء |
|
|
|
513 |
|
00:38:16,930 --> 00:38:22,050 |
|
او .. او كله سواء كانت احنا شدينا العضلة بطريقة |
|
|
|
514 |
|
00:38:22,050 --> 00:38:26,730 |
|
عنيفة او انها كانت بتعمل فعلا يعنيDynamic |
|
|
|
515 |
|
00:38:26,730 --> 00:38:30,150 |
|
contraction أو overloaded يعني نسميها زي ما بيصير |
|
|
|
516 |
|
00:38:30,150 --> 00:38:33,370 |
|
مع لعيبة الكورة هو بروح بشوت الكورة بعمل sudden |
|
|
|
517 |
|
00:38:33,370 --> 00:38:37,770 |
|
contraction في العضلة أو خلّينا نقول vigorous |
|
|
|
518 |
|
00:38:37,770 --> 00:38:42,390 |
|
contraction في العضلة فبصير فيه تمزق لبعض خيوط |
|
|
|
519 |
|
00:38:42,390 --> 00:38:44,910 |
|
العضلة The severity of the tissue damage depends |
|
|
|
520 |
|
00:38:44,910 --> 00:38:50,120 |
|
on the magnitude of theThe rate of the force |
|
|
|
521 |
|
00:38:50,120 --> 00:38:54,740 |
|
application and the strength of a musculotendinous |
|
|
|
522 |
|
00:38:54,740 --> 00:38:59,080 |
|
structure وهذا طبعا إشي طبيعي، طبعا قداش ال force |
|
|
|
523 |
|
00:38:59,080 --> 00:39:04,260 |
|
exerted، قداش ال rate، كام مرة، ال strength بعت |
|
|
|
524 |
|
00:39:04,260 --> 00:39:08,180 |
|
العضلة أو ال musculotendinous structure اللي هو |
|
|
|
525 |
|
00:39:08,180 --> 00:39:11,320 |
|
خلّيني أقول التناغم والانسجام بين ال contractile و |
|
|
|
526 |
|
00:39:11,320 --> 00:39:15,200 |
|
ال non contractile elements اللي موجودة في العضلة |
|
|
|
527 |
|
00:39:15,480 --> 00:39:18,820 |
|
طبعاً إلها تلاتة من الـ grades الـ mild والمدرت |
|
|
|
528 |
|
00:39:18,820 --> 00:39:22,500 |
|
والسيفير الـ mild are characterized by minimal |
|
|
|
529 |
|
00:39:22,500 --> 00:39:26,260 |
|
structural disruption and rapid return to the |
|
|
|
530 |
|
00:39:26,260 --> 00:39:31,020 |
|
normal function وهذه يعني يدوب يكون فيها شوية |
|
|
|
531 |
|
00:39:31,020 --> 00:39:35,040 |
|
خلينا نقول تمزق ال moderate associated with |
|
|
|
532 |
|
00:39:35,040 --> 00:39:41,140 |
|
partial tearمثلما يحدث في المسلسل عادة قريب من |
|
|
|
533 |
|
00:39:41,140 --> 00:39:46,240 |
|
الـmyotendinous يعني جانكشن بين المسلسل والتندون |
|
|
|
534 |
|
00:39:46,240 --> 00:39:51,360 |
|
وبين بعض الاختلافات الفنقشن أما سيفير فهي complete |
|
|
|
535 |
|
00:39:51,360 --> 00:39:55,010 |
|
أو near completeTissue disruption فيها انقطاع |
|
|
|
536 |
|
00:39:55,010 --> 00:39:58,590 |
|
وكمان عندنا complete functional loss وعندنا marked |
|
|
|
537 |
|
00:39:58,590 --> 00:40:03,510 |
|
hemorrhage and swelling لأنه بيصير فيه هروب للدم |
|
|
|
538 |
|
00:40:03,510 --> 00:40:09,160 |
|
لأنه صار قطع في الأنسجة تبع العضلةأما ال muscle |
|
|
|
539 |
|
00:40:09,160 --> 00:40:13,020 |
|
contusion كلنا بنتعرضله و خاصة اللاعبين الكورة أو |
|
|
|
540 |
|
00:40:13,020 --> 00:40:15,700 |
|
اللاعبين الرياضيين اللي بتعرضوا أو اللاعبين ال |
|
|
|
541 |
|
00:40:15,700 --> 00:40:18,940 |
|
boxers و غيرهم يتبعون ال basketball و ال football |
|
|
|
542 |
|
00:40:18,940 --> 00:40:21,820 |
|
لما بيكونوا بيخبطوا و بيقعدوا اللاعيبة يخبطوا في |
|
|
|
543 |
|
00:40:21,820 --> 00:40:24,720 |
|
بعضهم ال muscle contusion ال muscle injury |
|
|
|
544 |
|
00:40:24,720 --> 00:40:28,070 |
|
happened as a result of rightdirect compression |
|
|
|
545 |
|
00:40:28,070 --> 00:40:30,990 |
|
impact which causes intramuscular hemorrhage، |
|
|
|
546 |
|
00:40:30,990 --> 00:40:34,070 |
|
الدربات اللي احنا بنشوفها في رجلانا و في ايدانا، |
|
|
|
547 |
|
00:40:34,070 --> 00:40:37,110 |
|
نتيجة للخطاط اللي احنا باخدها و احنا مش دارين |
|
|
|
548 |
|
00:40:37,110 --> 00:40:41,350 |
|
بالنا أو اللعيبة الكرة لما الathletes بيدربوا في |
|
|
|
549 |
|
00:40:41,350 --> 00:40:47,590 |
|
بعضهم و بتصير في عندهم ال muscle contusionأما ال |
|
|
|
550 |
|
00:40:47,590 --> 00:40:52,110 |
|
exercise induced injury فهذه اللي بتفضلوا حدراتكوا |
|
|
|
551 |
|
00:40:52,110 --> 00:40:55,410 |
|
بتروحوا على الجيمنات و أول ما بتبدوا بتبدوا بخمسين |
|
|
|
552 |
|
00:40:55,410 --> 00:41:03,270 |
|
squat و خمسين push up و خمسين curl و خمسين set ups |
|
|
|
553 |
|
00:41:03,270 --> 00:41:07,430 |
|
فبتلاقوا بتروحواأول يوم بتكونوا حلوين ومبسوطين، |
|
|
|
554 |
|
00:41:07,430 --> 00:41:10,270 |
|
تاني يوم بتلاقوا بيفضل muscle soreness، بتبدو |
|
|
|
555 |
|
00:41:10,270 --> 00:41:14,410 |
|
عضلات بطنكم توجعكوا، بتصيروا من الدحكة تعيطوا، |
|
|
|
556 |
|
00:41:14,410 --> 00:41:18,970 |
|
فأكيد هذا بيصير ال exercise induced injury نتيجة |
|
|
|
557 |
|
00:41:18,970 --> 00:41:25,040 |
|
التمرين المفاجئ والغير معتاد هذا في فترة قصيرةيبقى |
|
|
|
558 |
|
00:41:25,040 --> 00:41:29,700 |
|
الـ injury results from connective and contractile |
|
|
|
559 |
|
00:41:29,700 --> 00:41:33,180 |
|
tissue disruption following exercise characterized |
|

560 |
|
00:41:33,180 --> 00:41:36,240 |
|
by local tenderness with stiffness restriction للـ |
